New high-sensitivity search for neutron to mirror-neutron oscillations at the PSI UCN source

N. J. Ayres, Z. Berezhiani, G. Bison +19

In a search for potential signals of neutron (n) to mirror-neutron (n') oscillations, a collaboration centered at the Paul Scherrer Institute (PSI) investigated the remaining param…

Measurement of the neutron incoherent scattering length of Hg using stored ultracold neutrons

C. Abel, K. Bodek, E. Chanel +35

We present the first direct measurement of the neutron incoherent scattering length of Hg. The measurement was performed with the Ramsey apparatus of the neutron electric…

A first extraction of the weak magnetism form factor and Fierz interference term from the In Sn Gamow-Teller transition

L. De Keukeleere, D. Rozpedzik, N. Severijns +5

Spectrum shape measurements in nuclear decay can be used to test physics beyond the Standard Model with results being complementary to high-energy collider experiments. In part…

Search for an interaction mediated by axion-like particles with ultracold neutrons at the PSI

N. J. Ayres, G. Bison, K. Bodek +44

We report on a search for a new, short-range, spin-dependent interaction using a modified version of the experimental apparatus used to measure the permanent neutron electric dipol…

In-situ measurement of the velocity spectrum of ultracold neutrons and its evolution using an oscillating detector

D. Rozpedzik, K. Bodek, K. Kirch +5

Ultracold neutrons (UCNs) are used in experiments investigating fundamental interactions, testing the Standard Model of particle physics and searching for phenomena beyond it. Know…

Search for ultralight axion dark matter in a side-band analysis of a 199Hg free-spin precession signal

C. Abel, N. J. Ayres, G. Ban +35

Ultra-low-mass axions are a viable dark matter candidate and may form a coherently oscillating classical field. Nuclear spins in experiments on Earth might couple to this oscillati…

values of the mirror transitions and the weak magnetism induced current in allowed nuclear decay

N. Severijns, L. Hayen, V. De Leebeeck +4

In recent years a number of correlation measurements in nuclear decay have been performed reaching a precision of the order of 1\% and below and it is expected that even higher…

Johnson-Nyquist Noise Effects in Neutron Electric-Dipole-Moment Experiments

N. J. Ayres, G. Ban, G. Bison +37

Magnetic Johnson-Nyquist noise (JNN) originating from metal electrodes, used to create a static electric field in neutron electric-dipole-moment (nEDM) experiments, may limit the s…

Statistical sensitivity of the nEDM apparatus at PSI to neutron mirror-neutron oscillations

C. Abel, N. Ayres, G. Bison +33

The neutron and its hypothetical mirror counterpart, a sterile state degenerate in mass, could spontaneously mix in a process much faster than the neutron -decay. Two groups hav…
